This study is to investigate the effect of CPR education on the knowledge, attitude, and self-efficacy of kindergarten, elementary, and secondary teachers. For the study, a total of 176 kindergartens, elementary schools, and secondary school teachers in J province who received CPR education at an Emergency Medical Education Center from March 21 to June 20, 2023 were surveyed. For the collected data, SPSS WIN 20.0 was used to analyze general characteristics, knowledge, attitude, self-efficacy, and educational program effects. As a result of the study, the knowledge score after education (t=-15.93, p<.001), attitude score (t=-5.11, p<.001), self-efficacy score (t=-12.52, p<.001) was significantly increased. After the education by experts, knowledge, attitude, and self-efficacy improved, and it is thought that the increase in knowledge increased attitude and self-efficacy. This is a result proving that the CPR education of the Emergency Medical Education Center was effective. Therefore, it is necessary to find ways for effective CPR education.

In automobile chassis system, the inflow of dust particle weakens durability of automobile's components increasing for wear and friction. Especially, the inflow of dust particle in rubber-seal makes noise and has a bad influence upon life-time of automobile's components. In this study friction and wear characteristics of rubber-seal for the inflow of dust patricle were investigated using the sliding wear tester. The test is a type of ball-on-disk ; ball is a steel, disk is a rubber-seal, and We use a SiO₂ particle, because SiO₂ particle is a main ingredient of dust.
